What we know of Odysseus` time on the island of Ogygia appears mainly in Book 5 of the Odyssey. Calypso was a nymph, daughter of Atlas, the Titan who bore the weight of the world on his shoulders. She was an immortal and wanted Odysseus as a husband, although Odysseus wanted to return to his wife, Penelope. He is described as spending his days on the island sitting by the shore on the rocks and weeping, looking out over the see, and wishing he could leave and go home. Homer also describes him as spending his nights in bed with the Calypso, and implies a sexual relationship.
How to put this in an appropriate way, lets just say he cheats on Penelope, eats and sleeps.
